International guidelines have progressively addressed global warming which is caused by the greenhouse effect. The greenhouse effect originates from the atmosphere's gases which trap sunlight which, as a consequence, causes an increase in global surface temperature. Carbon dioxide is one of these greenhouse gases and is mainly produced by anthropogenic emissions. The urgency of removing atmospheric carbon dioxide from the atmosphere to reduce the greenhouse effect has initiated the development of methods to covert carbon dioxide into valuable products. One approach that was developed is the photocatalytic transformation of CO. Photocatalysis addresses environmental issues by transferring CO into value added chemicals by mimicking the natural photosynthesis process. During this process, the photocatalytic system is excited by light energy. CO is adsorbed at the catalytic metal centers where it is subsequently reduced. To overcome several obstacles for achieving an efficient photocatalytic reduction process, the use of metal-containing polymers as photocatalysts for carbon dioxide reduction is highlighted in this review. The attention of this manuscript is directed towards recent advances in material design and mechanistic details of the process using different polymeric materials and photocatalysts.
国际指南已逐步应对由温室效应导致的全球变暖问题。温室效应源于大气中的气体，这些气体捕获阳光，进而导致全球地表温度升高。二氧化碳是这些温室气体之一，主要由人为排放产生。为减少温室效应而从大气中去除二氧化碳的紧迫性引发了将二氧化碳转化为有价值产品的方法的开发。已开发出的一种方法是二氧化碳的光催化转化。光催化通过模仿自然光合作用过程将二氧化碳转化为增值化学品来解决环境问题。在此过程中，光催化系统由光能激发。二氧化碳吸附在催化金属中心，随后在那里被还原。为克服实现高效光催化还原过程的若干障碍，本综述重点介绍了使用含金属聚合物作为二氧化碳还原光催化剂的情况。本手稿关注的是使用不同聚合物材料和光催化剂的材料设计最新进展以及该过程的机理细节。
